Using rgba in CSS · Issue #1775 · NativeScript/NativeScript · GitHub

This 8 digit hex color works in the NativeScript framework:

.drawer-button {
    background-color: #003751E4;
}
.drawer-button:highlighted {
    background-color: #FF3751E4;
}

However we should support something by CSS specs like:

.drawer-button {
    background-color: rgba(55, 81, 228, 0);
}
.drawer-button:highlighted {
    background-color: rgba(55, 81, 228, 1);
}

However the second throws on button tap:

JS ERROR Error: Invalid value rgba(55, 82, 228, 1) for property backgroundColor
